Kinetostatics of Rotationally Reciprocating Stirred Tank Planetary Actuator

摘要

Mechanical stirrers are widely used in chemical, petrochemical, food, construction and many other industries. Currently, a large number of stirred tank actuators with various types of the impeller motion have been developed, and at the moment the most promising constructions are rotationally reciprocating stirred tanks, since they make it possible to ensure high intensity of heat and mass transfer processes in the reactor, to eliminate stagnant zones and to increase the velocity gradient of the stirred liquid. As an actuator, the author proposes to use a planetary gear with elliptical gearwheels, which allows to convert the rotational motion of the motor shaft into a rotationally reciprocating motion of the impeller. For the design and manufacture of stirred tank, it is necessary to investigate its kinetostatics. In the article, the force analysis of the planetary actuator of the mixing device was carried out, as a result of which the design schemes were obtained and expressions were found for determining reactions in kinematic pairs. This will allow further calculations of the elements of kinematic pairs and links for strength, as well as determining the efficiency of the actuator.
